Climate Change is quite noticeable impact on Antarctica. Warmer layers of water, rising from the depths of influence even on the ice sheet the land, melting ice, descending into the sea. According to a study by British scientists, from 674 glaciers of the Peninsula at least 596 retreat. Melting and collapse of large ice shelves, threatening a rapid rise in Global sea level. there is a similar and rather large (and very unusual) glaciers. Denman the glacier is located in the Eastern part of Antarctica is on the canyon to a depth of 3 500 metres — this place is the deepest on land in the world. The glacier reaches 39 miles in length and from 13 to 19 kilometres wide. Recently, scientists carried out a detailed mapping of the glacier and found that an...

Environmental Scientists from Stanford University gave the first description of potential transmission of the novel coronavirus SARS-CoV-2 in the environment and factors influencing its spread. The results were published in the journal Environmental Science & Technology. lately, a huge number of scientific articles on the genetic structure of the virus that causes COVID-19, and its impact on the human body. However, as it spreads in the environment and infrastructure facilities, especially in water and air, remains virtually unknown. Recently, the national science Foundation of the USA opened funding of a project to study the migration of coronaviruses between skin and other materials, exposure to ultraviolet light and sunlight, as well as the connection...

What are the characteristics of tests for COVID-19, and the threat of existing rapid tests? The coronavirus has no distinctive symptoms. As a good impersonator, he masquerades as a normal flu or an ordinary cold. To find out, on whose back you were not to pay a high price for a performance of "the double" is to jeopardize the life of yourself and your family, as soon as possible to expose a coronavirus. Testing is the only way to understand the cold you picked up or COVID-19. Recognized in the world is a test, which detects specific for Wuhan virus genetic sequences. Of the benefits, the coronavirus can be detected from the first days of its ingestion. In most cases, the test results are accurate, since RNA virus looking for a proven method of PCR. Of the...

Each epidemic has its anti-heroes — so-called superastronomical, which managed to infect a lot of people sometimes not knowing that sick. The most famous Typhoid Mary caused in the early twentieth century, two waves of typhoid fever in new York. The SARS pandemic of 2003, the sad role played by Dr. Liu Sanglung, which makes the virus SARS-CoV got directly to the four countries. There are similar examples with the current COVID-19. Before the pandemic, severe acute respiratory syndrome SARS, better known as SARS, broke out in 2003-2004, the CDC was guided by the 20/80 rule, whereby 80 percent of all infections in any population occur in 20 percent media. Research has shown that the SARS epidemic played a key role individuals, without whom, perhaps, nothing...

American virologist Charles Calisher predicted that the pandemic coronavirus will last for years to come. About it and how it will flow. Kalisher noted that the pandemic will last until then, until they invent an effective vaccine. He stressed that the virus infected millions of people, and the non-infected can become carriers during the second wave of the epidemic. In this case, all countries are infected and the virus could spread across the planet, said the specialist. "The situation could change at any time. Imagine what they can achieve epidemic in regions and countries that are absolutely not prepared to it," said a virologist. He also said that this is not the last virus that threatens humanity: on the planet about three million undiscovered viruses....

This feature of the researchers explain this high rate of infection. A group of scientists on the example of patients with coronavirus were hospitalized in Hong Kong, has established the most dangerous period of infection, when COVID-19 most active and represents the maximum danger not only for the media but for everyone in contact with them. According to a study published in the scientific journal The Lancet, during the first week after symptoms of the disease carrier COVID-19 maximally contagious, and after 7 days the number of coronavirus in the saliva of man begins to decline. As noted by one of the authors, representative of the Hong Kong University Kelvin Kai-WAN, this was the pattern of the saliva of each of the 23 analyzed patients, regardless of...

1. On March 25, 2020 number of people isolated in their homes due to quarantine measures, amounted to more than 1/3 of the population. 2. Weekly applications for unemployment benefits in the US filed for 3.28 million against the expected 1.5 million, which was a record figure for many decades the history of the United States. In applications for benefits in the lead of California, where in recent days the number of persons who applied for benefits rose by 4000%, and payments were deferred for up to 3 weeks due to system overload. In some places in the United States of applications for benefits received so many that visitors bring down government websites. 3. As shown in the video below, which started the collapse of the economy, the US government has poured...

In China died the man who rode the bus to work. It checked for a new type of coronavirus, but the test gave a negative result. But in the patient's body found traces of Hantavirus. When this was reported by Chinese media, has risen the hype: we did not have enough of the second pandemic. But really, this time nothing to fear. As coronaviruses, Hantaviruses is a whole family that was identified 40 years ago, but individual members were known before. They normally infect mice, rats and other small mammals, and they transmit them to man. But rodents, these viruses do no harm, and humans cause disease. Hantaviruses in North and South America can cause cardiopulmonary (i.e., affecting the heart and lungs) syndrome that resembles the flu, but more often leads to...

Scientists believe that the infection COVID-19 can infect the human reproductive system. Russian scientists do not rule out the emergence of infertility in survivors coronavirus. According to experts, the ACE2 receptor, through which the coronavirus enters cells, is highly expressed in the testes. At least 6 dead from COVID-19 patients caused by infection of severe acute respiratory syndrome (SARS) led to orchitis, inflammation of the testicles. In the testes was noted the widespread destruction of germ cells, a small number or absence of spermatozoa in the seminiferous tubules, thickened basement membrane and infiltration of leukocytes. "Already today we know that 73% is infected with the virus SARS-CoV-2, the disease is asymptomatic. But recent...

Scientists have been able to explain why a vast region in the national Park years to rise and fall again. Yellowstone national Park, situated right on the volcano, known for its geysers and thermal springs. They form the whole of the valley with lakes and hot mineral streams. One of these valleys is called the basin Norris is the hottest and most dynamic thermal area in the Park. In recent decades, this area seemed to breathe, rising, falling a few inches. Between 1996 and 2004, an area the size of more than 46 km2 has risen by 11.9 inches, and then dropped to 7.1 cm for the next eight years. Then, in the period from late 2013 to early 2014, the region unexpectedly rose again to 15 inches. In March, near the basin of the Norris earthquake with a magnitude...

Yesterday in Moscow, it was deceptive weather. Under clouds and sun, but chilly wind blew so out of the closet I had to get down. In itself it's business as usual in the capital forever it is cold, overcast. It is surprising — that is outside the window at the weekend, with great accuracy was known at the end of last week. 20-30 years ago this was still dreaming. Websites and mobile apps with hourly weather forecasts — sometimes they give even to individual areas, if the city is large — have become something taken for granted. Because it seems that to make a prediction a little more complex than open the website: ran the program, pressed a few buttons and you're done. But in reality, the calculation of the future the weather is comparable to the mapping of...

Federal medical-biological Agency (FMBA) expects to receive first results of the testing of the prototype vaccine against the new coronavirus infection by June 2020, and the finished vaccine can be obtained within 11 months. On this portal, "the Future of Russia. National projects", which is operated by TASS, the press service of the FMBA. "First results of the vaccine trial 2019-nCoV (the original name of the virus, its official name now – SARS-CoV-2 – approx. TASS) is expected in June of 2020, the second phase is scheduled for completion by the third quarter of 2020. Preclinical studies can take up to 6 months, the first phase of clinical trials will take up to 5 months. the Minister noted that usually the second and third phase take up to 15 months...

In an effort to stop the spread of coronavirus, governments around the world have imposed severe restrictions on movement and travel. And now it turns out, these orders there was one unintended and quite unexpected consequence: the reduction or total suspension of labor migration, which is the cornerstone of food production. After the U.S. Embassy in Mexico announced the end of the interviews for seasonal farmers, American manufacturers, preparing for the harvest, warning of the devastating effect of this decision on the fruit and vegetable market. similar problems will face the same producers of meat and dairy products because work in this sector is also seasonal and local workforce there. Exactly the same situation in slaughterhouses/dairy farms and in...

A Mathematical model of uncontrolled "explosive" spread of viral diseases, created by the staff of the Samara national research University named after the Queen, may be useful in predicting new uncontrolled outbreaks of coronavirus infection, reported the press service of the Russian University. Scientists of the Samara University and the Autonomous University of Barcelona previously developed a mathematical model of the spread of dangerous viral infections depending on many factors. "Particular emphasis in their research, the scientists made on mathematical modeling of critical situations arising in the course of the disease in the population. The model demonstrates the possibility and the uncontrolled development of events in the case of the explosive...

One of the developers of the Russian vaccines against coronavirus infection albert Rizvanov, the employee of the Kazan (Volga region) Federal University, told TASS that the domestic prototype of the preparation will appear not earlier than in six months. Time of the vaccine, as the scientist, depends on how many research groups will be attracted to this work. the Scientist noted that it is very important to prove the effectiveness and safety of the vaccine. He recalled that, for example, the drug against human immunodeficiency virus (HIV), scientists are searching for more than two decades, and while neither version of the vaccine was not effective. "Often to develop a vaccine – it's not even half the battle, and one-tenth, because the most difficult thing...
